Usually a large male will lead a gorilla family. This can be a silverback, and males of 11 or 12 years of age are the ones that go grey in this manner. 5 people found this useful.
Fetal movement will usually be felt regularly after the 20th week of pregnancy. Any change in fetal movement (other than a 1-2 hour sleep cycle that some fetuses have) should be discussed with your physician. Decreased or absent fetal movement may be a sign of fetal distress. Kick tests (fetal movement counts) are used to monitor fetal wellbeing. You should monitor fetal movements (not just kicks) over a period of time (30-60 minutes). There is no right or wrong number of movements. You are trying to establish a baseline of fetal movements for your baby.
Most fetuses will develop a movement pattern you can predict. Some move more in the morning, some in the evening, Dr. Keller says. If you notice something different, go somewhere quiet, lie on your side, and concentrate on the baby with your hand on your stomach. If he moves a couple of times in a half hour, you're probably fine. If you don't feel your baby move, call your doctor.
